Well, you haven't made any withdrawal from CryptoGames yet. That's why the your minimum withdrawal limit is equivalent to 0.001 BTC, which is 362 DOGE at this moment. The min withdrawal limit is equivalent to 0.0005 BTC from the second withdrawal. You may find this information in their FAQ page. The min withdrawal amount is showing 182 DOGE on my account as it isn't my first withdrawal.

BTW, you can adjust the withdrawal fee and use 3 DOGE as the fee. No casino or website allows the user to withdraw Dogecoin with 0.01 DOGE fee (except those casinos where the withdrawal free is zero).
